I think you'd need to check to see who normally posts or lurks out of season before jumping to such a conclusion.
Anyone currently admitted to hospital, or worse, is very unlikely to vote in your poll so there's a very obvious potential statistical bias in your analysis here.
Almost certainly more than 20,000 dead so far in the UK
Adult population, about 65 million ... so about .03%
GOT has something like 30,000 active users.
Simple maths means that, if the average GOT member is representative of the demographics of the country ( they won't be, but bear with me ), then
GOT COVID Deaths = 30,000 * 20,000/ 65,000,000 = 9
Plainly most deaths are of people 60+ and GOT users will, on average, be younger than the average age in the UK, and some active users will be from countries with less scary death rates, so it won't be that bad, but, chances are, a few active users won't see us play a game again because of COVID-19.
